powermt set dev_inuse_to_array_report
Enables device report to the array.
Syntax
powermt set dev_inuse_to_array_report={on|off} [class=<class>|all] [proto={scsi|nvme|all}]Description
powermt set dev_inuse_to_array_report enables or disables device report to the array. User has to specify class option to enable or disable this feature for an array. This feature is available for PowerMaxOS 5978 microcode and above. PowerPath sends the application name which is using the device. PowerPath also sends if the device is mounted on the host and the last time the device was in use. This information is sent to array once in a day. This feature is persistent across host restart.
Options
- dev_inuse_to_array_report={on|off}
- on enables device report to the array.
off disables device report to the array.
- class={all|netapp|symm|vnx|clariion|vplex|invista|hitachi|hpxp|ess|xtremio|unity|sc|generic|powerstore}
- Limits the command to the specified type of storage system. all specifies all storage-system types. The default is all.
- proto={scsi|nvme|all}
- Limits the command to devices of the specified storage protocol. all speciifes both SCSI and NVMe storage protocol devices. The default is scsi.
